Urban Wastewater Treatment

Urban wastewater management is a crucial challenge in the small and medium towns situated in the developing countries worldwide. These towns are also facing an increasing gap between infrastructure and population growth. A conventional approach to curb these problems is the application of cost-intensive electro-mechanical sewerage technologies, as adopted in developed countries. The first part of this paper derives a set of indicators to framework a sustainable urban wastewater treatment system by reviewing the current state of wastewater management in developing countries, for example, the sample case study being India. The second part evaluates the potential performance of the proposed alternative in-situ hydroponic vetiver system (HVS) against those set of sustainability indicators by reviewing the worldwide performance of the HVS. The objective of this paper is to assess the potential viability of the HVS as a sustainable and cost-effective alternative for developing countries. The current analysis can aid in mainstreaming the use of HVS in policy making and urban planning.

<p>The relationship between women, technology manifestation, and likely prospects in the developing world is discussed in this manuscript. Using India as a case study, the paper goes on to discuss how ontology and epistemology views utilised in AI (Artificial Intelligence) and robotics will affect women's prospects in developing countries. Women in developing countries, notably in South Asia, are perceived as doing domestic work and are underrepresented in high-level professions. They are disproportionately underemployed and face prejudice in the workplace. The purpose of this study is to determine if the introduction of AI would exacerbate the already precarious situation of women in the developing world or if it would serve as a liberating force. While studies on the impact of AI on women have been undertaken in developed countries, there has been less research in developing countries. This manuscript attempts to fill that need.</p>

The Cost

While the ACTH1–24 test has some well-documented shortcomings, it is the most widely used test to diagnose primary and secondary adrenal insufficiency. However, this synthetic ACTH preparation is not readily available in some countries. Research from India has demonstrated that using a long-acting porcine sequence ACTH has similar diagnostic performance to ACTH1–24 at around 25% of the cost. This may allow access to a robust test for adrenal insufficiency to developing countries and potentially allow thousands of patients to be identified and appropriately treated.

Internationalization of Research and Development (R&D) allows transnational companies (TNC) to access different and important resources overseas, which may lead to the improvement of their technological innovation. The literature in this field has been mostly created from studies of TNCs coming from developed countries. This chapter presents some of the main topics the literature addresses on R&D internationalization, then it will explore and verify how companies in developing countries internationalize their R&D activities. In order to do so, a bibliographic review about strategies of internationalization of TNC operations, as well as motivating factors and management of R&D internationalization have been conducted. The chapter finishes by presenting a case study about international R&D conducted in a Brazilian TNC. The results enabled to evidence that, like developed countries TNCs, developing countries’ companies also seem to perform internationalization of R&D activities with very similar characteristics.

Lower Complexity

Upper extremity prostheses are a scarce necessity in less developed countries due to the lack of medical facilities, economic resources, and prevalent warfare. Prostheses have become a growing need as fifty-thousand amputations occur annually, with the current market being focused primarily on lower extremities. Leg prostheses have received much more attention and success than their upper extremity counterparts, due to their lower complexity that also yields lower cost. Prosthetic legs only need to fulfill basic motions such as walking and running, as opposed to the more complicated hands that encompass 22 degrees of motion. In less developed countries with few medical facilities, amputees need to travel long distances to find treatment. The objective is to design an affordable and easily assembled body-powered, below-elbow prosthetic device for adults that provides basic arm function and can be widely distributed in developing countries. Therefore, cost, availability, functionality, and simplicity are the primary considerations of the design.

Urban Wastewater Treatment

The principle of cost recovery established by the Water Framework Directive underlines the need for tax rates, which can raise enough revenue to finance the cost of treatments applied to wastewater. The objective of this research is to gain an understanding the different types of charges related to urban wastewater treatment that can be levied by the authorities responsible for this service. This paper also aims to determine whether these taxes contribute to guaranteeing the economic feasibility of the wastewater treatment plants. The proposed methodological approach is applied to 18 municipalities of a province in southern Europe in 2017. The results confirm that in most of these cases, the taxes levied do not guarantee adequate tax revenues to cover the running, maintenance and investment costs of municipal wastewater treatment plants. This situation leads to a lack of financial self-sufficiency in the wastewater management service, meaning that the imbalance between income and expenditure has to be covered by government subsidies. The results of this study will help guide authorities around the world that are in charge of managing urban wastewater treatment services.

Technological Strength

The integrated circuit (IC) industry is the foundation of the information industry, and its level of development is an important manifestation of the economic and technological strength of a country. At present, the IC industry is primarily monopolised by developed countries. Although China is the world’s largest consumer of semiconductors, it has a disproportionately small international market share of production and a very low domestic chip self-sufficiency rate, lagging far behind Europe, the United States, Japan, and South Korea. The process of promoting the development of China’s IC industry ecosystem is discussed based on a case study of Tsinghua Unigroup and the observation and analysis of its recent international mergers and acquisitions. The resulting conclusions suggest valuable mechanisms that could benefit the technological improvement of late-developing countries and help them close the gap with more developed countries. Relevant theory for the industrial ecosystem is enriched, providing a useful reference for the development of the IC industry in late-developing countries.
